OBJECTIVES Multi-vessel coronary artery disease (MVCAD) has long been recognized as an important predictor of adverse outcomes in patients with chronic stable angina. The aim of this study is to investigate the relationship between hematologic parameters and impairment of left ventricular systolic functions in patients with stable MVCAD.
STUDY DESIGN Patients (n=202) with stable angina and MVCAD were included in this study. According to the left ventricle ejection fraction (LVEF) determined by echocardiography, patients were divided into two groups as the preserved group (LVEF >50%) and the impaired group (LVEF <50%). The preserved group consisted of 106 patients and the impaired group consisted of 96 patients.
RESULTS The frequency of diabetes mellitus was significantly higher in the impaired group compared to the preserved group (respectively, 50% vs. 33%, p=0.01). High sensitivity C-reactive protein (hs-CRP) levels and, neutrophil/lymphocyte ratio (N/L ratio) were significantly higher in the impaired group than in the preserved group (3.9±2.4 vs. 7.9±3.8, p<0.001; 2.7±0.7 vs. 3.9±1.2, p<0.001, respectively). There was a significant correlation between LVEF, N/L ratio and hs-CRP; hs-CRP and N/L ratio were positively correlated (r=0.584; p<0.001), and LVEF was negatively correlated with both hs-CRP and N/L ratio (r=-0.48, p<0.001 and r=-0.43, p<0.001, respectively). A N/L ratio >3.0 had 77% sensitivity and 68% specificity in predicting left ventricular dysfunction in patients with stable MVCAD. In multivariate analysis, N/L ratio (OR: 2.456, <95% Cl 2.0564.166; p<0.001) was an independent predictor of left ventricular dysfunction in stable patients with MVCAD.
CONCLUSION N/L ratio and hs-CRP, which is inexpensive and easily measurable in the laboratory, is independently associated with impaired LV systolic functions in patients with stable MVCAD.
